'Uncircumcised In Heart' in the Bible

Egypt, and Judah, and Edom, and the children of Ammon, and Moab, and all that have the corners of their beard cut off, that dwell in the wilderness: for all the nations are uncircumcised, and all the house of Israel are uncircumcised in heart.

in that ye have brought strangers, uncircumcised in heart and uncircumcised in flesh, to be in my sanctuary, to profane it, even my house, when ye offered my bread, the fat and the blood; and they have broken my covenant besides all your abominations.

Thus saith the Lord Jehovah: No stranger, uncircumcised in heart and uncircumcised in flesh, shall enter into my sanctuary, of any stranger that is among the children of Israel.

O stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Spirit; as your fathers, ye also.
